NFTs listed on Marketplace can be purchased according to the method specified by the seller. If an NFT is unlisted, you can make an offer to buy it.
There are three methods the seller can specify. In the case of a limit price sale, a purchase is made when a purchase is requested at the specified price, and in the case of an auction sale, a buyer who meets the requirements for the specified auction method makes the final purchase. (Refer to the information below for bidding methods according to the auction type.)
